However, if I enter "sourceURL":"https%3A%2F%2F%5Bwowza-ip-address%5D%3A1935%2Fvod%2Fmp4%3Asample.mp4%2Fplaylist.m3u8",

the recording will not play. It worked a week ago.

But - and this is very strange - if I leave off "https%3A%2F%2F%5Bwowza-ip-address%5D%3A1935%2F" at the start and "%2Fplaylist.m3u8" at the end, it works - the player must have somehow cached my wowza-ip-address, or head office uses my [wowza-player-license-key] to get it from records.
